Modular multilevel structure of a high power dual active bridge DC transformer with stepped two-level output
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)This paper addresses the issues of dc voltage matching and dc fault protection in potential super-grids. An approach for high power dc-dc conversion is proposed and analyzed. A front-to-front connection of modular-multilevel ... -
The transition arm multilevel converter - A concept for medium and high voltage DC-DC transformers
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper proposes a dc/ac converter topology where each phase leg comprises a conventional series switch valve in one arm and a series connection of half-bridge chopper cells in the other arm. Operation with trapezoidal ...
